This application is a continuation application of U.S. Utility patent application Ser. No. 13/802,231 filed Mar. 13, 2013, the entire disclosure of which is herein incorporated by reference.

FIELD

The subject matter described herein relates to an injection site information cap and method for use in providing information to recordkeeping systems to automatically document caregiver identification, patient care activity, and/or procedural steps in the use of and/or care of a medication injection site.

BACKGROUND

Many health care procedures involve IV medication administrations. The type of medication and timing of administration are important to record in order to provide healthcare providers real-time information on the conduct of the procedure and the completion of a medical record. Some protocols require quick medication administrations with limited time for documentation and record keeping. Others require completion and verification of medication administration manually to ensure proper patient care and accounting for use of medications.

Injectable medications and fluids are frequently utilized by healthcare providers (caregivers) in the care of patients in the hospital, in pre-hospital emergency medical services (EMS) and at alternate care sites (including skilled nursing facilities, home health and hospice settings). Caregivers can include medical doctors, registered nurses, EMS paramedics, dentists and other licensed healthcare practitioners. Accurate documentation of what, when and how much medication and/or IV fluid is given to a patient is required by healthcare institutions, governmental agencies and regulatory oversight agencies. This is especially true when the IV fluid being administered to the patient is a medication or blood product. The type of IV fluid and the timing of administration are important to record in order to provide healthcare providers real-time information on the conduct of the procedure and the completion of a medical record. Some protocols require quick IV fluid administrations with limited time for documentation and record keeping. Others require completion and verification of manually administered IV fluids to ensure proper patient care and accounting for use of IV fluids.

Additionally, to ensure proper patient safety and limit exposure to catheter-related bloodstream infections (CRBSI), vascular access ports (injection sites) require careful disinfection and careful management of the patient's IV site for patency. Absent these activities, needleless injection sites can become contaminated and patient vascular access can become infiltrated or blocked. When these situations occur, patient safety is compromised resulting in infection, pain, longer hospital stays and even death. Hospital costs for continued patient care increase and are not reimbursed by third party payers.

New automated documentation systems for medication administrations will likely help in the tracking of medication injections, but none have addressed the documentation of proper IV site care and the management of needleless injection sites for infection control or IV site for patency. Manual use of alcohol swabs or sterile caps containing a disinfectant solution are gaining popularity for disinfecting IV injection sites and controlling CRBSI. When caps are left attached to IV luer access needless valves they can disinfect and protect the IV site. To date, these activities are often not documented, rarely time tracked and even less likely to be identified by caregiver.

Other patient care activity and procedural steps such as obtaining lab samples, assisting in respiratory therapy, dietary management also require timely documentation. Manual documentation often results in accuracy errors, missed notations and undocumented activity due to fast paced patient care with limited resources. A better system could result in less error, increased billing accuracy, reduced paperwork and more time for caregivers to focus on patient care. Tracking of who did what and when at the point of care can be improved.

SUMMARY

In one aspect, an injection site information cap includes a housing, a cover portion, an engagement portion configured to couple to and cover an injection port of an injection site and at least one information element on the cover portion that is positioned to be automatically sensed by at least one sensor of the injection site when the engagement portion is coupled to or is being coupled to the medication injection port.

The engagement portion can include a female luer lock thread configured to be coupled to a male luer lock thread on the injection port.

The at least one information element can be encoded with one or more of: mechanically encoded information, magnetically encoded information, a near field communication (NFC) tag, and a radio frequency identification (RFID) tag.

The at least one information element can include optically encoded information. The optically encoded information can include at least one bar code. The at least one bar code can be sensed by the at least one sensor as the cover portion is circumferentially rotated or translated linearly on the axial centerline of the luer lock.

The injection site information cap can include a disinfectant to disinfect the injection port upon the coupling of the engagement portion with the injection port. The engagement portion can be further configured to seal the injection port of the injection site.

The injection port can be fluidically coupled to a patient and/or to a fluid wasting reservoir.

The information element can encapsulate data characterizing one or more of: a disinfection state of the injection port, a caregiver identification, an identification of a patient, a procedural step performed in connection with care of the patient, a state of waste disposal, a lab sample, respiratory management for the patient, and dietary management for the patient.

Some or all of the housing can be color coded with one of a plurality of color categories. Each color category can characterize one or more of: caregiver identification, a patient care procedural activity, a laboratory sample, a state of the injection port, a fluid injected into the injection port, and a state of a patient. The at least one sensor or a different sensor can, in some variations, detect the color. In addition, in some variations, at least the information element is color coded with one of a plurality of color categories, each color category characterizing one or more of: care giver identification, a patient care procedural activity, a laboratory sample, a state of the injection port, a fluid injected into the injection port, and a state of a patient.

The information element can be affixed to an outer surface of the cover portion or it can be integral to an outer surface of the cover portion.

In a further aspect, an injection site information cap can include multiple engagement portions. For example, a medication injection site can comprise a housing including a first engagement portion on the housing configured to couple to and cover a first injection port of a first injection site. At least one first information element on an outer surface of the first engagement portion of the housing can be positioned to be automatically sensed by at least one first sensor of the first injection site when the first engagement portion is coupled to or is being coupled to the first injection port, a second engagement portion on the housing can be configured to couple to and cover a second injection port of a second injection site, and at least one second information element on an outer surface of the second engagement portion of the housing can be positioned to be automatically sensed by at least one second sensor of the second injection site when the second engagement portion is coupled to or is being coupled to the second injection port.

The at least one of the first engagement portion and the second engagement portion can comprises a female luer lock thread configured to couple to a male luer lock thread on the injection port. The at least one first information element and the at least one second information element can be encoded with one or more of: mechanically encoded information, magnetically encoded information, a near field communication (NFC) tag, and a radio frequency identification (RFID) tag. The at least one second information element can be optically encoded information. The optically encoded information can be at least one bar code. The at least one bar code can be sensed by the at least one sensor as the housing is circumferentially rotated.

The information cap can further comprise: a disinfectant to disinfect at least one of the first injection port upon the coupling of the first engagement portion to the first injection port. The at least one of the first injection port and the second injection port can be fluidically coupled to a patient. The at least one of the first injection port and the second injection port can be fluidically coupled to a fluid wasting reservoir.

The injection site information cap can include one or more of the at least one first information element and the at least one second information element to encapsulate data characterizing one or more of: a disinfection state of the injection port, a caregiver identification, an identification of a patient, a procedural step performed in connection with care of the patient, a state of waste disposal, a lab sample, respiratory management for the patient, and dietary management for the patient. The information cap can include at least a portion of the housing, and/or the information element, to be color coded with one of a plurality of color categories, each color category characterizing one or more of: caregiver identification, a patient care procedural activity, a laboratory sample, a state of the injection port, a fluid injected into the injection port, and a state of a patient.

The one or more of the at least one first information element and the at least one second information element can be affixed to an outer surface of the housing. The at least one first information element and the at least one second information element can be integral to an outer surface of the housing. The at least one of the first engagement portion and the second engagement portion can be further configured to seal and/or cover the injection port of the injection site. The first injection site and the second injection site can be physically connected to each other.

In some variations, the at least one first information element is different from the at least one second information element while in other variations the elements are the same (identical). Each engagement portion can have identical features such as disinfectant or they can differ (one side has disinfectant while the other does not). The housing can be color coded in different manners similar to a single engagement portion injection cap.

The first engagement portion can be positioned opposite the second engagement portion. In other variations, the first engagement portion is positioned at an angle or otherwise askew as compared to a center line of the second engagement portion. In other variations, the housing can be flexible.

In a further interrelated aspect, an apparatus includes a first engagement portion on the housing configured to cover a injection port, at least one first information element on an outer surface of the first engagement portion of the housing positioned to be automatically sensed by at least one first sensor of the injection site when the first engagement portion is coupled to or is being coupled to the injection port; a second engagement portion on the housing configured to cover the injection port, and at least one second information element on an outer surface of the second engagement portion of the housing positioned to be automatically sensed by at least one sensor of the injection site when the second engagement portion is coupled to or is being coupled to the injection port.

The injection site information caps as described herein can be used in connection with various methods. For example, one method can include receiving information from a medication delivery apparatus characterizing at least one information element on a cap covering an injection port of the medication delivery apparatus, associating the received information with data comprising one or more of: a disinfection state of the injection port, a caregiver identification, an identification of a patient, a procedural step performed in connection with care of the patient, a state of waste disposal, a lab sample, respiratory management for the patient, and dietary management for the patient, and promoting the associated data.

The medication delivery apparatus (injection site) can include a housing, a fluid conduit at least partially extending within the housing and configured to deliver medication within a medication container to the patient, an injection port extending from an external surface of the housing and configured to be coupled to a fluid outlet of the medication container (the medication port being fluidically and directly coupled to the fluid conduit), and at least one sensor disposed within the housing to sense the at least one information element on the information cap. In some variations, the medication delivery apparatus can also include a transmitter within the housing to wirelessly transmit information generated by the at least one sensor to a remote data collection system, and a self-contained power source within the housing powering the at least one sensor and the transmitter.

Promoting the associated data can include one or more of: displaying the associated data, storing the associated data into a physical storage device, loading the associated data into memory, and transmitting the associated data to a remote computing system.

Computer program products are also described that comprise nontransitory computer readable media storing instructions, which when executed one or more data processor of one or more computing systems, causes at least one data processor to perform operations herein. Similarly, computer systems are also described that may include one or more data processors and a memory coupled to the one or more data processors. The memory may temporarily or permanently store instructions that cause at least one processor to perform one or more of the operations described herein. In addition, methods can be implemented by one or more data processors either within a single computing system or distributed among two or more computing systems. Such computing systems can be connected and can exchange data and/or commands or other instructions or the like via one or more connections, including but not limited to a connection over a network (e.g. the Internet, a wireless wide area network, a local area network, a wide area network, a wired network, or the like), via a direct connection between one or more of the multiple computing systems, etc.

The subject matter described herein provides many advantages. For example, the current subject matter allows for compact injection port systems that automatically identify activity at the injection site. The fluid injection port is sufficiently small to be placed on a standard IV line (and to be self-supporting) allowing it to be used in multiple situations including on-site paramedic treatments, during ambulance delivery of patients, as well as medical facilities such as emergency rooms/intensive care units/operating rooms/general care. Moreover, as medical staff (e.g., doctors, nurses, paramedics, etc.) are accustomed to handling Y-sites on IV lines and the current subject matter requires little, if any, behavior modifications while allowing for intelligent logging of patient care activities within normal workflow. In addition, the compact nature of the fluid injection port obviates the need for a larger tabletop or cradle bar code unit which can be cumbersome during code blue or other emergency events and which can require much needed space (displacing other required equipment). In addition, the current subject matter utilizes a wireless interface and does not require wires for communication of information to a data collection system which could interfere with or complicate patient care activity. Data received by the data collection system can be actively displayed in real-time providing clearly visible information to the medical staff keeping all informed and up-to-date. Furthermore, the current subject matter reduces manual record keeping and other activities that can tend to detract from the needed attention to a patient. Automated record keeping provides accurate records and frees up the health care provider's time enabling improved patient care.

The details of one or more variations of the subject matter described herein are set forth in the accompanying drawings and the description below. Other features and advantages of the subject matter described herein will be apparent from the description and drawings, and from the claims.

FIG. 1 depicts an intelligent injection site 4 directly coupled to a “Y” site of an IV fluid delivery tubing set 11. Connection of an intelligent injection site can be to other injection sites such as stopcocks, manifolds, “T” sites, venous access devices, catheters, etc. Details of intelligent injection site 4 are discussed in the referenced patent applications entitled “Medication Injection Site and Data Collection System”. Tubing set 11 is attached at one end to a fluid source for delivery of fluids to a patient. Distal end of tubing set 11 is attached to vascular access device 16 (needle, catheter, etc.). Located in between each end of tubing set 11 is a “Y” site providing and injection site for additional fluids and medications to be administered to a patient. Fluid containers can be coupled to intelligent injection site 4 by inlet 13 and luer lock threads 56. Outlet 14 of intelligent injection site 4 can be coupled to the “Y” site providing for fluid delivery to a patient into inlet 13, through conduit 10 and out of output 14. Intelligent injection site 4 can include emitter 31 and identification sensor 18 positioned such that when an information element 24 is in the field of view or within a predefined distance, circuit 30 can image and transmit 36 information contained on information element 24 to data collection system 6. Data collection system 6 can transmit 50 data collected to medical information system 52. Additionally, intelligent injection site 4 can include fluid delivery sensor 60, power source 19 and indicator 35.

FIG. 2 depicts a medication container 20 (syringe example) with an added information element 24 forming an encoded medication container 33. Information element 24 can be a label for example and can contain encoded information 12. Encoded medication container 33 can contain medication 22 for injection into a medication injection site. Medication container 33 can include outlet 16 to deliver medication 22 to a medication injection site. Details of information element 24 and its coupling to medication container 33 are discussed in the referenced patent applications entitled “Medication Container Encoding, Verification, and Identification”.

FIG. 3 illustrates system 3 with an encoded medication container 33 attached to housing 5 of an intelligent injection site 4. Fluid outlet 16 of medication container 33 can be coupled to fluid inlet 13 of intelligent injection site 4. Coupling can automatically activate emitter 31 and identification sensor 18 to read information element 24. Data from information element 24 can be transmitted 36 by transmitter 34 to data collection system 6. Data collection system 6 can identify, display, time stamp and record the information content of information element 24. Medication container 33 can expel medication 22 through conduit 10, through outlet 14 and into an injection site coupled to a patient. Fluid delivery sensor 60 (not shown) can measure the expelled fluid 22 and transmit 36 data to data collection system 6. Data collection system 6 can display, time stamp and record the data from fluid delivery sensor 60.

FIG. 4 depicts an injection site cap 100 that can include information element 24 forming information cap 200. The injection site information cap 200 can have a shape and size configured to couple to and cover (and in some cases seal) an injection port. Injection site information cap 200 can include luer lock threads 154 on the inner diameter. Additionally, injection site information cap 200 can include a disinfectant 102 to disinfect an injection site (“Y” site) on IV tubing set 11 as shown in FIG. 1. Disinfectant 102 can be 70% alcohol or any other type of IV site disinfectant. Injection site information cap 200 can limit contact with injection site 4 fluid inlet 13 to only the surface of housing 5 (fluid inlet surface 13 and/or external threads 56) and not enter the fluid pathway.

In addition to system 3 for encoded medication containers as shown in FIG. 3, FIG. 5 depicts a non-medication container information system 2. System 2 can include information element 24, information cap 200, intelligent injection site 4 and data collection system 6. Information cap 200 can be made from plastic (polycarbonate, polystyrene, polyvinylchloride, etc.), can be provided sterile and can be enclosed in a sealed foil package for single use. Information cap 200 can attach to inlet 13 by engaging internal luer lock threads 154 with external threads 56 on intelligent injection site 4. Information cap 200 can be rotated clockwise to engage luer lock threads 154 and 56. Information cap 200 can be rotated counter clockwise to disengage luer lock threads 154 and 56 and remove information cap 200. Information cap 200 can be a push-on type without luer lock threads 154. Information cap 200 can cover, protect and/or disinfect inlet 13.

Information cap 200 can be colored to designate a category. The color can be part of housing 5, part of information element 24 (background color) or part of data element 12. Categories can include any assigned color or type. For example color assignments could be: red=lab sample taken, orange=caregiver ID, yellow=medication given, green=billing charge, blue=physical therapy activity, violet=lab sample taken, white=sedation activity. Other colors and/or categories can be included. The color can be detected by identification sensor 18 and transmitted to the data collection system in addition to the information contained in the information element. The information can be detected by identification sensor 18 when a specific wavelength light (ultraviolet, infrared, etc), a specific RF or magnetic frequency, or a combination of frequency and wavelength is emitted from emitter 31.

Information cap 200 can be used with intelligent injection site 4 for caregiver identification during medication waste disposal. In this use case, intelligent injection site 4 can be connected to a medication waste disposal receptacle. Information cap 200 can contain caregiver ID information and document who and when medication waste is disposed. This can be followed by an encoded medication container and injection of waste medication into the receptacle. Fluid delivery sensor 60 can measure the volume of waste disposed. A second caregiver can verify waste disposal by immediately following waste disposal with the attachment of a second information cap 200 having a different caregiver ID. Information detected on caregivers information caps 200 and encoded medication container waste disposed volume can be transmitted 36 to data collection system 6, time stamped and transmitted 50 to medical information system 52.

FIG. 6 illustrates system 2 with information cap 200 fully coupled to intelligent injection site 4. Coupling information cap 200 to intelligent injection site 4 can automatically activate emitter 31 and identification sensor 18 to read information element 24. Data from information element 24 can be transmitted 36 by transmitter 34 to data collection system 6. Data collection system 6 can identify, display, time stamp and record the information content of information element 24. Data collection system 6 can display, time stamp and record the data from identification sensor 18. Data collection system 6 can transmit 50 this data to medical information system 52.

Information element 24 on information cap 200 can be any one or more of: mechanically encoded information, magnetically encoded information, a near field communication (NFC) tag, a radio frequency readable information (RFID tag). The information element 24 can also or alternatively comprise optically encoded information and the identification sensor 18 can comprise an optical emitter and an optical detector to read the optically encoded information. The identification sensor 18 can include an optical emitter LED to illuminate the information element 24 and an optical detector such as a camera (charge coupled device—CCD). The identification sensor 18 can read information from the information element 24 as a result of relative motion of the information cap relative to injection site 4. The identification sensor 18 can read information from the information element 24 in response to mechanically coupling the information cap 200 to the injection site 4.

Information cap 200 can carry an information element 24 that provides detectable information indicative of an activity performed by a caregiver or a patient. The activity can be any one or more of: disinfection of the injection site, caregiver identification (name, ID number, employee number), a procedural step performed (IV site visual assessment, a surgical procedure step, an intensive care unit activity, an emergency medical services {EMS} activity), confirmation of waste disposal (unused controlled substances, contaminated waste, etc.), other patient care activity such as obtaining a lab sample from a patient, assisting in respiratory therapy of a patient, dietary management of a patient, and many other patient care activities at home, in the field, or in a hospital environment where recordation is appropriate. The data encapsulated by element 24 can be detected by an intelligent injection site and processed either locally or by transmitting to a remote computing system.

The identification sensor 18 can include an optical emitter/detector pair 31 that detects encoded information contained on information element 24 (a sleeve or label wrapped around injection site information cap 100). The identification sensor 18 can comprise a plurality of sensors to detect information element 24. In some variations, the identification sensors can be sensors such as optical, magnetic, mechanical, conductive, switchable RFID and/or proximity sensors. In other variations, identification sensor 18 can be optical and can include an illumination source (emitter) such as an LED and a detection source (detector) such as a camera (CCD). Sensor circuit 30 can provide signal processing and connects identification sensor 18 to transmitter 34. The identification sensor 18 can be directly coupled to power source 19.

FIGS. 7 & 8 illustrate two alternative information caps 200 with extended surfaces to assist users in attaching and detaching information cap 200 from/to injection site 4. FIG. 7 illustrates an extended cap housing with a stripped grip section 104. FIG. 8 illustrates a narrower extended surface 106 forming a finger grip handle. Additionally, information element 24 can include human readable information 26 (“Disinfected”) to enable a user to verify the information content prior to information cap 200 use.

FIG. 9 illustrates two alternatives of applying information element 24 to injection site cap 100. As shown at the top, information element 24 can slide over (110) and attach to injection site cap 100 forming assembled information cap 200. On the bottom, information element 24 can wrap around (120) and attach to injection site cap 100 forming assembled information cap 200. Information element 24 can be a label or any one of: an optical image (1 dimensional barcode, 2 dimensional barcode, symbol, image or picture), a magnetic image (magnetic strip on an identification card/badge/ID tag), a Near Field Communication (NFC) tag, an RFID tag, and/or mechanically encoded information. Details are included in aforementioned patent applications.

FIG. 10 depicts an information cap 400 with two active ends (A and B). Injection site cap 300 can have two ends A and B. Each end can have disinfectant 102 and luer lock threads 154. Injection site cap 300 can have two information elements (24A and 24B), one at each end to form injection site information cap 400. Information element 24A can be the same as information element 24B to allow multiple uses (e.g. two injection site disinfections). Information element 24A can be different from information element 24B allowing two different activities to be recorded. One could be “Disinfected” (24A) and the other could be a procedural step “Procedure X” (24B). The sequence and timing of use can be determined by the user. For example: End A can be used prior to a medication injection to provide information 24A (disinfection of the injection site). A medication can then be administered using an encoded syringe (see FIG. 3). End B can be used to provide information 24B (document the procedural step “X”). End B can remain coupled to the intelligent injection site 4 to protect it from contamination. The data collection system 6 can record and timestamp each information element (24A and 24B) as well as the medication administration. Maintaining End B coupled to the injection site can be recorded by the data collection system (“site protected”, End B=not removed). At a later time, when End B is removed from the injection site, the injection site can be recorded as unprotected. This same recordation can be completed using single ended information cap 200. It will be appreciated that information cap 400 can have more than two active ends. In some variations, the housing of information cap 400 can be flexible and optionally elongated.

FIG. 11 illustrates two methods of packaging and sealing the open end of information cap 200 (or 400). To the left is a simple peel open tab foil/poly seal 108. To the right is a foil/poly sealed pouch 109 with a tare open strip. Any number of other methods of packaging and sealing information cap 200 can be envisioned. Each method can protect information cap 200 internally prior to use, maintain sterility and contain the disinfectant solution.

 6. The cap as in claim 1, further comprising a stripped grip section.
 7. The cap as in claim 1, further comprising an extended surface forming a finger grip handle, wherein the extended surface has a narrower diameter than a remainder of the cap.
 8. The cap as in claim 1, wherein the at least one information element is removably coupled to the cap.
 9. The cap as in claim 1, wherein the at least one information element is configured to slide over and attach to the cap.
 10. The cap as in claim 1, wherein the at least one information element is configured to wrap around and attach to the cap.
 11. The cap as in claim 1, wherein the engagement portion is a push on type configured to push on to the injection port without luer lock threads.
 12. The cap as in claim 1, wherein the injection port is fluidically coupled to one of a patient and a fluid wasting reservoir.
 13. The cap as in claim 1, wherein the at least one information element further encapsulates data characterizing each of: a caregiver identification, an identification of a patient, a procedural step performed in connection with care of the patient, a state of waste disposal, a lab sample, respiratory management for the patient, and dietary management for the patient.
 14. The cap as in claim 1, wherein at least one of the at least one information element and the cap is color coded with one of a plurality of color categories, each color category characterizing one or more of: caregiver identification, a patient care procedural activity, a laboratory sample, a state of the injection port, a fluid injected into the injection port, and a state of a patient.
 15. The cap as in claim 1, wherein the at least one information element is integral to an outer surface of the cap.
 16. The cap as in claim 1, wherein the engagement portion is further configured to fluidically seal the injection port of the injection site.
 17. A cap comprising: a first end and an opposite second end; a first engagement portion on the first end of the cap configured to removably couple to and cover a first injection port of a first injection site; at least one first information element on an outer surface of the first engagement portion of the cap positioned to be automatically sensed by at least one first sensor of the first injection site when the first engagement portion is coupled to or is being coupled to the first injection port; a second engagement portion on the opposite second end of the cap configured to couple to and cover a second injection port of a second injection site; and at least one second information element on an outer surface of the second engagement portion of the cap positioned to be automatically sensed by at least one second sensor of the second injection site when the second engagement portion is coupled to or is being coupled to the second injection port, wherein the at least one first information element is configured to record a first type of activity, and wherein the at least one second information element is configured to record a second type of activity different than the first type of activity.
 18. The cap as in claim 17, further comprising a disinfectant to disinfect the first injection port upon the coupling of the first engagement portion with the first injection port, wherein the at least one first information element encapsulates data characterizing a disinfection state of the first injection port, and wherein the at least one second information element encapsulates data characterizing a procedural step.
 19. The cap as in claim 18, wherein the at least one first information element comprises human readable information to enable a user to verify the disinfection state.
